SHOW KNOWN_FILE_ENTRY

See SHOW KFE.

SHOW LAN

Displays information contained in various local area network (LAN) data structures.

Format

SHOW LAN [/qualifier[,...]]


Parameters

None.

Qualifiers

/ATM

Specifies that asynchronous transfer mode (ATM) information for the LAN be displayed.

/CLIENT=name

Specifies that information be displayed for the specified client. Valid client designators are SCA, DECNET, LAT, MOPRC, TCPIP, DIAG, ELN, BIOS, LAST, USER, ARP, MOPDL, LOOP, BRIDGE, DNAME, ENCRY, DTIME, and LTM. The /CLIENT, /DEVICE, and /UNIT qualifiers are synonymous and mutually exclusive.

/COUNTERS

Specifies that the LAN station block (LSB) and unit control block (UCB) counters be displayed.

/CSMACD

Specifies that Carrier Sense Multiple Access with Collision Detect (CSMA/CD) information for the LAN be displayed. By default, both CSMA/CD and Fiber Distributed Data Interface (FDDI) information is displayed.

/DEVICE=name

Specifies that information be displayed for the specified device, unit, or client. For each LAN adapter on the system, there is one device and multiple users of that device called, units or clients. Device designators are specified in the format XXdn, where XX is the type of device, d is the device letter, and n is the unit number. The device letter and unit number are optional. The first unit, which is always present, is the template unit. These are specified as indicated in this example for a DEMNA called EX:
/DEVICE=EX---display all EX devices on the system
/DEVICE=EXA---display the first EX device only
/DEVICE=EXA0---display the first EXA unit
/DEVICE=SCA---display SCA unit
/DEVICE=LAT---display LAT units

Valid client names are listed in the /CLIENT=name qualifier. The /CLIENT, /DEVICE, and /UNIT qualifiers are synonymous and mutually exclusive.

/ELAN

Specifies information from an Emulated LAN (ELAN) that runs over an asynchronous transfer mode (ATM) network. The /ELAN qualifier displays the LAN Station Block (LSB) address, device state, and the LSB fields pertinent to an ELAN for both the parent ATM device and the ELAN pseudo-device drivers. It also specifies the name, description, parent device, state, and LAN emulation client (LEC) attributes of the ELAN.

The qualifier /ELAN used with the device qualifier (/ELAN/DEVICE=ELA) will only display information for the specified device or pseudo-device.

/ERRORS

Specifies that the LSB and UCB error counters be displayed.

/FDDI

Specifies that Fiber Distributed Data Interface (FDDI) information for the LAN be displayed. By default, both CSMA/CD and FDDI information is displayed.

/FULL

Specifies that all information from the LAN, LSB, and UCB data structures be displayed.

/INTERNAL

Specifies internal counters of the drivers by displaying the internal counters. If the /INTERNAL qualifier is used with the /DEVICE qualifier, the /INTERNAL specifies the internal counters of a specific driver.

/QUEUES

Specifies a listing of all queues, whether their status is valid or invalid, and all elements of the queues. If the /QUEUES qualifier is used with the /DEVICE qualifier, the /QUEUES specifies a specific queue.

/SOURCEROUTING

Specifies that the information in the source routing table maintained by the Token Ring driver be displayed.

/SUMMARY

Specifies that only a summary of LAN information (a list of flags, LSBs, UCBs, and base addresses) be printed. This is the default.

/TIMESTAMPS

Specifies that time information (such as start and stop times and error times) from the device and unit data structures be printed. SDA displays the data in chronological order.

/TR

Specifies that Token Ring information for the LAN be displayed.

/UNIT=name

Specifies that information be displayed for the specified unit. See the descriptions for /CLIENT=name and /DEVICE=name qualifiers.

/VCI

Specifies that information be displayed for the VMS Communication Interface Block (VCIB) for each LAN device with an active VCI user. If you use the /VCI qualifier with the /DEVICE qualifier, the VCIB is only displayed for the specified device.

Description

The SHOW LAN command displays information contained in various local area network (LAN) data structures. By default, or when the /SUMMARY qualifier is specified, SHOW LAN displays a list of flags, LSBs, UCBs, and base addresses. When the /FULL qualifier is specified, SHOW LAN displays all information found in the LAN, LSB, and UCB data structures.
